["Anoop Sam John (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-14179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14651417#comment-14651417 ] 

Anoop Sam John commented on HBASE-14179:
----------------------------------------

The 2nd catch is for the outer try block.  You can see the 1st one, after sleep() call comes within another catch block of the outer try catch.  So when the sleep happens if we have to catch the possible InterruptedException, we should have the catch block there. The outer catch block wont be able to catch it. (As the code is another block)
